Time‐Varying Hydroclimatic and Oceanic Controls on Arctic Submarine Groundwater Discharge Inferred Using Explainable AI

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Submarine groundwater discharge (SGD), an important component of coastal water and nutrient budgets, is challenging to monitor and predict in the Arctic given the remoteness and harsh conditions. Here, we used explainable artificial intelligence to quantify the time‐varying importance of hydroclimatic and oceanic drivers of SGD at an Arctic ...

Farm‐Scale Recharge Pits for Improving Local Groundwater Availability: Insights From a Hardrock Watershed in Rajasthan, India

World Water Policy, Volume 12, Issue 3, August 2026.
ABSTRACT Groundwater depletion is a major challenge in semiarid, hard‐rock regions where irrigation demands often exceed natural recharge. This study evaluates the effectiveness of farm‐scale recharge pits as a local, supplementary, and community‐managed groundwater recharge solution in the Dharta catchment of Rajasthan, India. Alongside check dams and

From Crisis to Resilience: Rethinking Urban Flooding and Groundwater Recharge in Bengaluru City, India

World Water Policy, Volume 12, Issue 3, August 2026.
ABSTRACT Bengaluru, a primary metropolitan centre in India, is currently grappling with the dual crises of urban flooding and severe groundwater depletion. These challenges are driven by rapid urbanization, which has seen built‐up areas increase from 42% to 86% over two decades, resulting in a dramatic loss of vegetation and wetlands.

Optimisation of Drop‐Sheet Sampling in Macadamia (Macadamia integrifolia) Orchards: An Optimised Method for Monitoring Insect Ecology

Austral Entomology, Volume 65, Issue 3, August 2026.
ABSTRACT Understanding orchard arthropod populations is a critical element of making strategic decisions regarding pest management. Therefore, it is paramount for farmers and crop consultants to use appropriate survey methods that provide a representative sample of orchard insect ecology. Currently, macadamia (Macadamia integrifolia) industry arthropod
